WINDOW SCREEN.

T all whom. it may concern Be it known that I, CARL G. FIORGNER, a citizen of the United States, residing at Chicago, in the county of Cook andidtate of Illinois, have invented certain newtand useful Improvements in Window Screens; and I do declare the :lollowing to be a full, clear,

and exact description of the invention, "such constructed in accordance with my inven-' as will enable others skilled in the art to which itappertains to make and use the same. I e o i 1:

My invention relates to improvements in vertically slidable closures, such as window screens and hasreference more particularly to screens designed primarily for. use in connection with the windows of passenger cars.

The principal object of the invention is to greatly simplify and improve. upon the constructions shown by my S. Patents Nos-1047828 of Dec. 12,1912 and 1071565- A further object is to provide unique.

means torholding the screen inlowered position, said means being controilable -by the arms above referred to.

Yet another object is to inake novel provision for 'detachably holding; the screen in engageinentv with its guides. ;5

With the foregoing and minor objects in view, the invention resides-in the novel sub- I jcct matter hereinafter described "and claimed, the description beingsupplemented by the accompany'ina drawings, i F lgure '1 is aside elevat on ot'ascree tion, showing also the vertical screen guides and the window frame which carriesthese.

Figure 20i's: ahorizontal sectionallview* on'line 20 .20of.Fig. 19. I V In the drawings "above briefly described, the'window: frame .1 and thersash or sashes p F igure 13 is a detail-vertical section as 8 indicated" by line 1313 of Fig. 7..

Figure 14 is a. detaiLVert-ical section on' instance in'Figs. 16, 17 and 18, the formation of each of the strips being such that its inner side is provided witha longitudinal groove or channel 3 which is preferably of substantially semicircular' form in transverse section. Slidably engaged with one of the strips 2 and having a rounded edge received in its groove is one vertical side 4 of a screen frame 5, the other vertical side 6 of thisframe havlng a rounded edge 7 which is spaced from the groove 3"of the other strip 2', the spacebeing occupied by a filler bar 8 which" is preferably of concavoconvex form in transverse section; so that its convex side '9 is resolvable within" the groove 3' of the last named strip2, while the concave side 10 of the .barreceives the rounded edge of the frame side 6. A spring projected latch boltll shown most clearly in Figs. 3, 17 and 18' is mounted in the upper side bar of the frame 5 and is normally forced by its spring into an opening '12 in the inner. side of the bar 8, whereby to hold this bar against rotation and to connect it rigidly with'the frame 5. When the latch bolt is in thisflposition, a shoulder 13 with which it is provided, thrusts outwardly against the bar 8 and therebyiyieldably holds the latter against its co-acting strip'2, so as'to exert a braking action which prevents accidental dropping of the screen when raising or lowering the same and manipulating the swinging arms yet to be described. When the bolt 11 is retracted as shown for instance in Fig. 18,- the fillerbar 8 may be turned about itslongitudinal axis, by means of a suitable finger pieee ld which is shown on said 'bar in Fig. 1. Thus, the concave side 10 of this bar and its convex side 9 are disengaged from the edge 7 and the grove 3 respectively,"sufficiently to permit the entire bar to be removed. This allows lateral play of the screen and consequently it may readily'be' removed from the window frame- Y V vAsjit is customary tore'move the screen at certain seasonsand again apply them at other 'tirhesjbut' is inadvisable to have the latch 11 of such nature that the passengers could release the same, lv prefer that this latch shall be totally confined within the upper bar of the screen frame 5, but inorder thatsaid latch n'iay be released by means of a suitable instrument, I form slot '15 in the frame'bar giving-access to a socket 16' in the latch: By inserting oneend of a; U shaped instrument such as that shown at 17 in Fig. 18, into the socket 16, the bolt 11 may easily be retracted, whereupon the other end of said instrument 17 may be passed into an opening 18 in the upper bar of the screen frame, thereby holding the latch released while the bar 8 is being turned. hen turning the bar, it is also necessary to move the finger grips toward each other and hold them by any suitable means such as a substantial duplicate of vthe device 17, whose ends may be engaged with said grips.

The numerals 20 designate a pair of ver tically swinging arms connected with the lower corners of the screen frame 5, said arms normally" lying against the screen frame when the latter is lowered. These arms are preferably of ch'annel form in transverse section as shown for instance in 5, 10 and 15, so as to lie under and of each arm 20 is provided with a finger 21 extending in the direction of its length and that the strips 2 are each provided with arec'ess 2 to receive the linger 21 of the ad jacentarm. This arrangement is also illustrated clearly in Fig. 3. The recess 2' is cut entirely through the inner side wall of the guide strip 2 so that the finger 21 may hook over the lower edge wall 23 of said rezess, whereby it cannot be disengaged until the screen 5 is moved slightly upward from its normal raised position. hen this is done, the finger 21 strikes a cam 24 at the upper end of'the recess 22 and hence is forced inwardly out of-alinement with the end wall 23. Thus, when the screen frame 5 is lowered. the finger 21 will not again engage said end wall 23, but the screen may be lowered, it. being of course understood that during the lowering operation, the arms 20 are again swung upwardly under the lower edge of the screen frame 5 so as to permit the latter to move entirely to its lowermost position.

' I prefer to ass'ociate'some suitable means withthe arms 20, for the purpose of holding the screen frame 5 in its lowered position. In the preferred form of my invention, I provide each of the arms 20'with a flat head 25 which passes through a slot 26 in the lower edge of the frame and is pivoted at 27 in a bifurcated plunger 28, the latter' being located within a lower corner of the frame:5 and being projected normally outward by a suitable spring. 29: "The head 25 is provided with a projecting nose 30 which,

when the arm 20 is. swung to its horizontal position as in Fight, is received in a notch 31in the inner side of the guide strip 2. It will thus be seen that the screen frame cannot be raised until the arm is pulled inwardly and the nose-thus disengaged from the notch 31- as indicated in Fig. 7.

It. is of-course understood that thecon struction just described is associated with each of the arms 20 andin order 'that both of these arms may be? simultaneously moved inwardly against the tension of the springs 29, I provide the free ends of said arms with finger grips 32 which are suiiiciently close together'when the arms 20 are horizontal to permit them to be moved toward each other by the thumbandforefinger of one hand: VVhen thesel grips are thus moved tot release the noses .30 from the notches '31, the arms 20' may be swung downwardly-as in Fig. 8, after the frame 5 has been raised sufliciently to permit this movement. Then by graspmgfthe fingergrips 82, the frame may beraised to the maximum amount and they-fingers 21 engaged with-the recesses 22- sov asitohold said frame-raised.- When the arms 20 stand :in the last named position, the noses'30 preferably abut the" stop sur faces or shoulders; 33 withinthe corners'of theiframeas shown in Fig-'8 sothat" the entire weight of the screen is taken from the pi'vots'27. [If desired, the heads, may each be provided with a fstopnose 34 to engage the stop shoulder 35 ontheplungzer 28 when the arm is lowered (see Fig. 8). These stop noses, 3 i may well engage the I stop surfaces or shoulders 33; when the arms 20 are horizontal as in Fig. 61 Thus, when the screen islowerechpossibly with quite a jar, there is no danger of'injuring the pivot P 2 1 1 1 a In thepreferred form sof construction, the vertical side bars 4 and 6 of the frame-5 are connected with the bottombar -byineans of 7 suitable corner blocks '36 extending into and to the frame 5 in the manner'shown, but as riveted to the adjacent ends of these bars,

and these corner blocks are preferably rea cessed to I'GCQIVQ the movable parts asso'" cia-ted with the pivotedends of the arms 20 as shown in several of the views. These corner blocks may of course be solid or hollow, and of any. desired configuration to obtain the desired results. I

The screen wire 37 is preferably secured this detail of'construction is'very similar to the corresponding construction of my previous patents, it need not be described in detail.

In connection with the features of construction above described, I may use a wear strip 8 interposed between the frame SlClQ' 4 and the adjacent guide strip'2,'as seen in "position.
